Problems solved by technology

However, this material is used in pavement engineering, and its construction requires heavy mechanical action, and there are many inconveniences as a roofing material.
Moreover, the treatment temperature of asphalt is 150°C, which does not significantly improve the smoke pollution generated by asphalt in the process.

Abstract

The invention discloses a low temperature construction asphalt planting roof root blocking material and a preparation and construction method thereof. The technical scheme includes the following steps: step 1, adding 20-30 parts of a cosolvent into 100 parts of matrix petroleum asphalt, and performing stirring and dissolving under a temperature of 40-50 DEG C so that viscous flowable matrix petroleum asphalt slurry can be obtained; step 2, separately adding 10-20 parts of methyl methacrylate or a derivative thereof, 1-2 parts of a promoter and 1-2 parts of a root blocking agent into the slurryobtained by the step one, and performing mixed reaction under shearing and stirring at normal temperature so that reaction matrix slurry can be obtained; and step 3, adding 1-2 parts of a photoinitiator into the reaction matrix slurry obtained by the step 2, and performing the mixed reaction under shearing and stirring at the normal temperature so that the root blocking material can be obtained.The method is simple in process, low in production cost and construction difficult, and therefore, the processing temperature of the root blocking material can be reduced, and the high temperature anti-deformation capability of the root blocking material can be enhanced.

Description

technical field [0001] The invention relates to the field of planted roofing materials, in particular to a low-temperature construction asphalt planted roof root-resistance material and a preparation and construction method thereof. Background technique [0002] Roof greening has the advantages of not occupying land resources, increasing urban greening area, improving air quality, beautifying urban landscape, alleviating the urban heat island effect, reducing the range of temperature fluctuations that the roof is subjected to, prolonging the life of the roof, reducing energy consumption of indoor air conditioners, etc. The advantages have become an important direction of green building technology, and are respected by professionals in ecological environment, planning, design and other fields around the world. However, it is unavoidable that the planted roof will damage the designed roof structure due to the puncture of the roots of the plants, causing large-scale water leaka...
